No: the 3 word address in one language is not a translation of the 3 words used in a different language version.
This is for various reasons. There is no one-to-one translation of many words between languages, so table.lamp.chair in English might have many different translations in different languages: it's linguistically not possible this way.
More importantly though, the what3words algorithm assigns words around the world according to where each language is spoken. This ensures that, for example, the most common, memorable Swahili words are used in 3 word addresses in Kenya and Tanzania, whereas the most common, memorable Turkish words will be in Turkey, and so on, with each language carefully crafted to be as effective as possible.
